Given numbers are 823,660,143

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 823,660,143 is 7061340.

Find LCM of 823,660,143 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

11 x 823 x 60 x 13 = 7061340

Therefore, the lowest common multiple of 823,660,143 is 7061340.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

823 x 660 x 143 = 77674740

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

823 : 1, 823

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

143 : 1, 11, 13, 143

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 823,660,143, is 1.

Now, the common factors can be found like this.

823:823

660:2x 2x 3x 5x 11

143:11x 13

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

11 = 11

Therefore, the value for common factors is 11.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 77674740/(1x11)

LCM = 77674740/11

LCM = 7061340

Thus, we can understand that the LCM of 823,660,143 is 7061340.
